Which element has the greatest number of valence electrons?

Sulfur (S)

Phosphorus (P)

Francium (Fr)

Beryllium (Be)

Expert Solution

Sulfur - [Ne]3s²3p⁴ (6 valence electrons)

Phosphorus - [Ne]3s²3p³ (5 valence electrons)

Francium - [Rn]7s¹ (1 valence electron)

Beryllium - [He]2s² (2 valence electrons)

Hence Sulfur has the greatest number of valence electrons.
